A few things in response: 1. Churches have a right to assert opinions and others, including me have a right to object to those opinions … and a responsibility when there is evidence that the opinions harm people. 2. The church hasn’t taught anything about homosexuality (meaning how to respond to people who are sexually attracted to members of the same gender) until the concept emerged in the 19th Century. 3. It’s common (now) for churches that have policies like no weddings for same gender couples, to essentially hide these policies, including not mentioning it from the pulpit. This is especially the case in the non-denominational sector where policies aren’t widely known. It’s only a non-issue for straight people not stigmatized by the policies once they are eventually unveiled (like when a same-gender couple wants to get married, or serve in some capacity from which they are banned.)
